Custom Electrical Testing Solutions — B2B Engineering Engagement

2026年05月12日

Off-the-shelf does not always fit. Here is the five-stage custom-instrument engagement model.

When Off-the-Shelf Does Not Fit

Most fleet buyers need standard EK Pro Suite instruments. But large utility, rail, and renewables customers sometimes need custom electrical testing solutions — modified ranges, custom UI, integrated logging, or proprietary connectors. EK Engineering engages on a five-stage B2B model.

Stage 1: Spec Workshop

  • EK and customer engineering teams meet (on-site or video).
  • Customer's measurement task documented end-to-end.
  • Off-the-shelf instrument compared to gap.
  • Custom delta defined: ranges, UI, accessories.
  • Output: spec document signed by both sides.

Stage 2: NRE Quote

EK quotes Non-Recurring Engineering cost (firmware, mechanical, calibration jig, certification re-test) and amortisation per unit at a defined volume. Customer approval required before Stage 3.

Stage 3: Prototype

  1. 3 - 5 prototype units delivered in 8 - 12 weeks.
  2. Customer evaluates against original spec for 30 days.
  3. Sign-off or revision loop.
  4. Iteration window: usually 1 - 2 cycles.

Stage 4: Qualification

  • Full IEC 61010 safety re-certification.
  • CAT rating verified by third party.
  • Calibration jig built and validated.
  • Production line trained.

Stage 5: Production

First production lot 50 - 100 units, full QC. Subsequent lots scale to forecast. EK guarantees 7-year support and spare parts for the custom variant.

Typical Use Cases

  • Rail traction: custom DC range to 4 kV.
  • Wind turbine: high-altitude derating + insulation tester variant.
  • Marine: full IP67 sealing + salt-fog tested.
  • Substation OEM: branded EK-G645 + EK-C350 + EK-C300 bundle.
